Picked up an 84 Interstate over the winter, running rough, actually thought it was only running on 3, not the case, but I do suspect # 3 carb has a problem, spark plug reads different than the others, all light tan to gray, but #3 is almost like its just clean (?) .... haven't checked the plugs for about 500 miles now, need to do that! Been running ATF and Seafoam with high octane / non ethanol gas doing some 80 mph/ 150 - 180 mile loops and its continually getting better. Issue is she just doesn't want to take a handful of throttle, easy throttle, lower rpms and she is smooth actually starting to get strong. Can actually feel the motor at 75/80 when giving some throttle do some rpm lurching as if she wants to break out of the box she's in! The carb rack probably really needs to come off for a rebuild, but in the mean time, I was wondering what if I opened up the tops and gave the diaphrams a once over, maybe shot some carb cleaner or ATF into the body let it soak and pull the bowel drain and dump it? Any thoughts you might have I'm all ears. Really irks me knowing there is a lot of power there I can't touch! ........................... and boy I do like riding the 84 compared to my 80, whole different feel, but if I'm not mistaken my 80 would eat up the 84 in a head to head!? .....
